We're all about the wind-powered LED rigs lately, but for some reason we're just not as captivated by the Firewinder LED windmill as we'd hoped to be. The vertical corkscrew features rows of white LEDs embedded in the blade's edge that brighten as the winds blow harder, which is definitely a neat concept, but in execution it looks more or less like a super-high-tech barber pole -- a look we're not certain we're willing to drop £99 ($200) for. Check the super-dramatic vid after the break.

There's no shortage of green solar- or wind-powered ways to juice up your gadgets these days, but rarely do we see a charger that employs both together -- along with the reliable old power grid -- for sweet, sweet redundancy. The Hymini from startup MINIWIZ was first conceived by founder Arthur Huang in an MIT business class, and combines a micro turbine generator with a 1200mA/h lithium ion rechargeable battery that can also be filled via USB, AC, or an optional array of up to four miniSOLAR solar panels. According to published specs, the device -- which has yet to be priced or released -- will operate at wind speeds between 9mph and 40mph, with a 20-minute session in 19mph winds providing enough power for between four minutes of talk time (cellphone) and forty minutes of music playback (flash-based DAP). Very promising indeed, yet of limited utility until we find a gadget that ensures we don't leave all these handy supplemental charging products in the bottom drawer of our desk when we actually need them.

Generally speaking, wind turbines have been reserved for more macro-scale operations, but a West Australian inventor "believes he has developed a way to generate electricity for homes using wind power." This residential approach utilizes a modular turbine that is minuscule enough to perch atop nearly any roof without causing too much unsightliness, and can create power for the house to consume as the wind pushes its blades. Additionally, Graeme Attey suggests that solar panels could be used in conjunction with his creation, giving you double the renewable energy opportunities (at least during the day). Currently, Mr. Attey's device is being partially funded by the West Australian government, and homeowners who toss one up on their crib could receive a rebate if in fact this is ready for commercialization next year.

Clogged highways and frustratingly waiting while your gas needle plummets to empty usually doesn't conjure up thoughts of green, but it seems like these very roads could become the source of a lot more energy. Several recent student designs have proposed that major roadways be retrofitted with various forms of wind energy collection devices, ranging from overhead turbines that collect energy from quickly-moving cars below to barrier panels (pictured after the jump) that harness the wind from closely passing vehicles moving in opposite directions. Ideally, the wind energy could then be sent back out to the grid to power nearby communities, light-rail transportation systems, or even intelligent billboards. Of course, most of these ideas are still in the research phase, and even if proven feasible, we can't imagine the up-front costs (or inconveniences of installing these things) to be minor, but we're sure that government subsidies should be able to to lend a helping hand.

Leave it to the makers of the first "solar shuttle" to actually hit its production schedule, as Venturi Automobiles is officially readying its Eclectic vehicle for a June 2007 launch. The "world's first" commercially available autonomous vehicle sports a "stylish, urban design," room for three, and never needs to get friendly with an AC outlet (although it can, if necessary) or fuel pump. This puppy is powered and recharged completely by renewable energy, be it sunlight or wind, as it houses a bevy of NiMH (NIV-7) liquid-cooled batteries that can be juiced up from the 2.5 square meters of photovoltaic cells atop its roof or a set of wind turbines that can be fixed to the vehicle while parked. Right on target, the company plans to launch a "limited run" of 200 in June, which will be white in color and demand around €24,000 ($31,421). As the learning curve kicks in and production costs sink, the vehicle price should ring up closer to €15,000 ($19,638) when it goes full scale in 2009, while a "single-seat utilitarian version" will compliment the flagship unit sometime in the future. So if you're thinking about ditching the whole "fill your car up" thing, you may still have time to get in on the pre-orders now being accepted for the first 20, but if history proves anything, it's doubtful.
